What does zymotic mean?
Zymotic is an uncommon adjective with two closely connected historical uses. Its basic sense means relating to fermentation, the biochemical process in which microorganisms transform substances such as sugars into alcohol, gases, or acids. Before modern germ theory was widely accepted, physicians also used the word for infectious or contagious diseases because they believed such illnesses were caused by fermentation-like processes in the body. Cholera, typhus, and other diseases were consequently discussed as zymotic diseases in nineteenth-century medicine. Today, the term is uncommon outside historical and specialized writing, and expressions such as zymotic disease can sound antiquated. Nevertheless, zymotic is useful because it records an important stage in the history of medicine, when fermentation supplied a general explanation for disease that was later displaced by evidence linking particular microbes to particular infections. The word derives ultimately from the Greek zymē, meaning leaven or fermenting substance.

Where does zymotic come from?
Zymotic comes from the Greek zymotikos, meaning fermentative or causing fermentation, which was formed from zymē, “leaven.” The word entered English in a scientific context before being used in historical medical writing for diseases attributed to fermentation. Its related English forms include zymosis, zyme, enzyme, and zymology, all reflecting the same Greek root.
